Emergence of Hematopoietic Progenitors in Culture
Around day 14, the endothelial and stromal cells fully cover the well surface and the first hematopoietic progenitors start to emerge from the EBs. Images show EBs in adherent culture at day 14 of differentiation. Stromal and endothelial cells appear as flat elongated cells and immature progenitors appear as bright aggregates of small round cells, which are not yet in suspension. Scale bar represents 100 μm.
